A skillful performance

You sigh and roll you eyes slightly as you move your hand to steadying the base while you begin to give a more earnest blow job to the bound man. You begin to wonder when you'd be considered done if he can ejaculate on command, but figure if you can **** him to have a more serious orgasm the reward might be enough for a vacation.

You begin swirling your tongue around the head and giving his shaft a luxurious bathing between bouts of short bobs, cocking your head back and forth with each stroke to increase his pleasure. You look up towards your father and see the group of researchers quite a bit more interested in your performance now, some of them openly masturbating. Even your dad looks more uncomfortable in his pants before, adjusting himself for long periods of time. Must be doing well!

The bound man begins chuckling at you lightly under his breath, slowly rising to a more full belly laugh that rocks the gurney. You take his cock out of your mouth for a moment to glare at him. "You'll never get me off that way, little cum slut. You can't even deep throat?"

He shoots another single shot of thick cum across your face as he begins to laugh at you again. You begin angrily swiping the medicine towards your mouth with your finger, but he sprays two more shots, one directly into your left eye, before you manage to get his back cock in your mouth for part of a third. You swallow the small offering you catch, but give up on rest after at least cleaning out your eye and sneaking it in your mouth around him. It still stings, so you keep it closed.

Guess you gotta do this with a facial now, you figure, resuming your work steadily deeper to ease yourself into a deep throat. He's pretty big, but a least he's smaller than that John guy you met earlier. In fact, you're rather surprised when you find it down to the hilt with hardly any discomfort at all! Guess it got stretched out a bit, somehow. You smile happily and take a few empty swallows to massage his cock with your throat muscles.

You begin taking long quick strokes while pausing occasionally at the hilt to swallow several times. He doesn't stand a chance now!
